Problem to play mp4 video in html5

I made a video play on a plane in editor mode, as soon as my character activates the sensor located on the floor.

My version of UE4 is 4.23 and every time I play on htlm5, everything works except the video.

I already tried to make the video by sequence of images, but both use the media player of UE4, which does not work to play any type of video in htlm5.

I’m looking for any solution to be able to play a video in html5

Same problem here.
Any development on this issue?
